FROM INDIANA SOCIETY OF ENGINEERS. 
By CHaAs. BROSSMANN. 
Mr. President and Gentlemen: I feel that is is an honor to address 
your meeting, and am glad to speak a few words of greeting on behalf of 
the Indiana Engineering Society. 
On your program I notice the names of more than one engineer and 
subjects relating to engineering work. I feel that the scientist and 
engineer need no introduction, for they have ever worked either together 
or in sequence for the betterment of man and civilization. 
On the vital questions relating to the physical development of our 
vast industrial system the scientist has made the work of the engineer 
possible. 
The first step belongs to your work. You took the initiative and ad- 
vanced radical though perhaps unappreciated theories, labored for years 
to prove them, and had to work and keep the courage of your convictions 
to establish your point beyond question. 
Your reward has not usually come from a grateful public, but you

I wish to mention one or two papers on your program, one “A List of 
Alge.” <A list of algee means nothing to a community, but when an entire 
water system becomes clogged with Crenothrix, they cry for the scientist 
to find the remedy. 
The subject, “The Problem of Sewage Disposal,’ does not appeal to a 
city until the stench is apparent, then succor from scientist and engineer 
is needed. 
Most of the papers to be read, touch upon the betterment of the human 
race, the conservation of its health, and the country’s resources. 
Today Dr. Von Lendenfeld investigates the organs of flight of the best 
flyers of the insect orders, Lepidoptera, Hymenoptera and Diptera. The 
public hears and smiles. 
Tomorrow the Wrights fly for hours in the upper air. The public sees 
and gasps in wonder and amazement. 
And so the scientist needs be the silent man. Carlyle says: “The 
noble silent men—scattered here and there—each in his department—
